Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCP2512B100RJS6 is determined by strict equivalence in the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 4.6W (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±150ppm/°C (exact match required)
• Operating Temperature Range: -65°C ~ 155°C (exact match required)
• Features: Moisture Resistant (exact match required)
• Number of Terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Tolerance may vary within the acceptable range for the application. Substitute parts must maintain all other electrical and mechanical specifications identically.

Parameter Comparison

Engineering Selection Recommendations

RCP2512W100RGEB qualifies as a direct substitute for RCP2512B100RJS6 based on identical electrical specifications, mechanical dimensions, and thermal characteristics. The substitute part offers improved tolerance (±2% versus ±5%), which provides tighter resistance accuracy without compromising compatibility.

The primary distinction is RoHS compliance status: RCP2512W100RGEB is ROHS3 compliant, while RCP2512B100RJS6 is RoHS non-compliant. Selection between these parts depends on regulatory and procurement requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can RCP2512W100RGEB replace RCP2512B100RJS6 in existing designs?

A: Yes. Both parts share identical resistance, power rating, package dimensions, thermal range, and composition. The substitute maintains full mechanical and electrical compatibility.

Q: What is the difference in tolerance between these parts?

A: RCP2512B100RJS6 has ±5% tolerance, while RCP2512W100RGEB has ±2% tolerance. The tighter tolerance of the substitute part does not affect interchangeability but provides improved resistance accuracy.

Q: Are there any environmental or compliance differences?

A: RCP2512W100RGEB is ROHS3 compliant, whereas RCP2512B100RJS6 is RoHS non-compliant. Both parts have identical moisture sensitivity levels and operating temperature ranges.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm) and maximum seated height of 0.025" (0.64mm).

Q: What determines substitution eligibility for 2512 chip resistors?

A: Substitution requires exact matching of resistance value, power rating, package type, composition, temperature coefficient, operating temperature range, and moisture resistance features. Tolerance may vary within acceptable application limits.
